    was trying to change the burned out bulb and the whole unit just shut down. Did not pop the household breaker as I tested the socket for current. Waited a while to see if replugging it in would reset but no luck. Another site I visited suggested that this symptom is a blown circuit board.

    Was microwaving rice. Heard this loud noise for about 2 seconds that sounded like a garbage disposal and then the panel went blank, no power. Did not trip any breakers. Dead - nothing. Help!

    Micro just quit, the display is dead, power outlet has current. My last Micro did the same thing, I gave it away after replacing it, the person I gave it to said all it needed was a fuse.

    Sure could use some help, I hate to toss something that is easy to fix.

    What was happening at the time it went out?

    Cooking? Just hit "Start"? Opened the door? Closed the door?

    If you can give me a little more detail I can probably steer you better.

Water may have leaked inside unit causing a short.the transformer output is about 1400 volts that feeds a large capacitor. a direct short can blow the transformer instantly or any support parts without time to burn something. creating little or no smell. I never sujest that a person
to try to repair a microwave oven because
the capacitor can still be charged and very lethal.

Hi I have a Samsung SMH9187 micowave that is dead (no display, light, fan, mirowave).


Sounds like the main fuse blew. It's either near where the power cord enters the cabinet, or behind the control panel (if an over the range unit).

You may also have some type of failure in the high voltage circuit; based on your description of the symptoms.

No power at display!


You've probably destroyed your magnetron, and the magnetron thermostat.

This kind of abuse will not be covered under warranty.

It will likely run about $75 for a technician to visit the home, $75 to do the work, $75-90 for the magnetron, and about $15 for the thermostat.

Upon startup, on high power, trips the circuit breaker. The microwave is on a dedicated 20 amp breaker. It's a recent vintage (2007) Kenmore unit, installed over a cooktop with the built in exhaust fan. I...


If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor. See here.

If it went dead several seconds after pressing the Start pad, that's usually a failing high-voltage transformer. See here.

If it goes dead or blows the breaker (or GFI) when you plug it in or open or close the door, then there's a problem with a door switch or door switch mount. See this file.

You can find exploded views and order parts by entering your model number (from the tag in or on the unit) at the Sears parts site.

BUT once you have the part number from the Sears site, you can often get the parts cheaper here.

There should also be a "mini-manual" (tech sheet) hidden inside the unit behind the control panel or hidden on the left side behind the grille, which is very helpful when troubleshooting, testing, and locating components.

I have a kenmore electric oven, turned on oven and range, a few minutes later I heard a pop, oven and range went dead, tripped the circuit breaker in the basement. We tried to turn the breaker back on,...


It appears your magneto or power supply has failed in this instance.

For replacement parts - head on over to PartSelect.com or RepairClinic.com and enter in your full model number for a full parts listing.
I recommend both sites because ...


FixYa has no affiliation with either site - I have been using and recommending them for years - trouble free.

PartSelect has a great schematic database for locating the part on your unit and great "testimonials" for each part that often times includes HOW-TO information.
RepairClinic has pictures of each part they sell and also a great how-to and troubleshooting for basic repairs.


If your unit has never been serviced - there should still be an original service manual enclosed in plastic taped to the inside of the shell.
In the service manual are Error codes, maintenance procedures, and troubleshooting steps you can follow.


Anything too complicated or beyond your scope should be handled by a professional.

If you think you want to tackle the repair - and have gotten stuck on a step - reply to your question and I will be glad to help you out.





Thanks for using FixYa - a 4 THUMBS rating is appreciated for answering your FREE question.

I have a Sharp Carousel II microwave oven mounted above the range. It went dead when I pushed the start switch. The circuit breaker to the unit was not tripped. I don't know where to find the model number...


Model number is on the side of the control or along he bottom of the frame. The control panel should be removable with a screw or 2 and sliding up to unlatch. the fuse is behind there. To remove it off the wall there is 2 screws coming down from the cabinet above and the unit tips towards you and lifts up off a lip on the back plate. Eric

Replace OTR Microwave


Thanks for responding. It is a EWave KOT-152UW. I think EWave is part of Magic Chef. I think it is the door switch. When I opened the microwave, the circuit breaker tripped. I reset the circuit breaker, and it worked for several days, but the last time, the microwave went dead. The reason I want to use the same bracket is it has through the wall (horizontal) venting to the outside, and I am not keen on trying to cut more holes.

NO POWER, POPPED CIRCUIT


Two possible causes.

First (and most likely) the circuit is being overloaded. This kitchen circuit may be shared with another appliance (like the refrigerator) which is drawing enough power when both are running to trip the breaker. A Typical kitchen circuit is 20 amp with #12 wiring. So an 1800 watt microwave might draw 13 or 14 amps while a fridge compressor kicking in can surpass 7 amps before it levels off. If this is an older home the kitchen may have a 15 amp circuit with #14 wiring. If the circuit is a 20 amp you will have to split the appliances onto separate circuits. (Under code a kitchen must have a minimum of 2 separate appliance circuits). If it is a 15 amp you might be able to split them as well or may be looking up upgrading the breaker and the wiring from 15amp #14 to 20 amp #12 (but you could still have the same problem).

The other possibility is a short or loose connection. If splitting appliances onto their own circuits doesn't fix this you would probably want an electrician to come in and check for other underlying causes which could represent a fire hazard.

Hope this helps.

No power from Whirlpool.


IF YOU HAVE THE MICRWAVE PLUGGED IN AND THE CIRCUIT BREAKER TRIPS IMMEDIATELY WHEN SET,
CHECK THE DOOR HOOKS THAT TRIP THE DOOR SWITCHES. BOTH SHOULD BE SPRING LOADED. THERE SHOULD BE TWO HOOKS ON THE DOOR. IF O.K., CHECK THE DOOR SWITCHES. THERE ARE AT LEAST THREE. IF ONE OF THEM IS SHORTED CLOSED,
THE MONITOR SWITCH WILL CAUSE A DEAD SHORT ACROSS THE FUSE. THE FUSE MAY BE HOLDING BETTER THAN YOUR CIRCUIT BREAKER.

Microwave quit working


If it went dead almost immediately after pressing the Start pad, that's usually a shorted high-voltage capacitor.

If it went dead a few seconds after pressing the Start pad, that's usually a failing high-voltage transformer.

It may also be the high-voltage rectifier diode.

If you or a friend decide to look into it, we have critical safety information and disassembly information at our site, linked here on Fixya: http://tinyurl.com/yzjozk

Feel free to post your brand and model so we might be able to give me specific info.
